    Can a loaded but disabled add-on to IE7 cause problems?

    I have disabled all add-ons that are not "Add-ons that run without requiring
    permission", i.e. certified add-ons.

    Still I have experienced one IE7 freeze so far, and now the question is if
    this freeze can have been caused by an add-on that has been loaded but also
    permanently disabled?

    If not the freeze must be caused by some authorized add-on or by IE7 itself.

    If an add-on can be the cause even when it is disabled I need advice on how
    I can (temporarily) prevent loading add-ons while searching for the culprit.

    Use the Manage Add-ons tool to determine which add-on is causing the

    1- Control Panel > Internet Options > Programs tab > 'Manage add-ons'
    button > 'Manage Add-ons' window.

    2- In the Show box, select 'Add-ons that have been used by Internet
    Explorer' to display /all add-ons that are installed on the computer/.
    For each item in this list, select the add-on, and then click Disable
    under Settings. When you have disabled all the items in this list, click OK.

    3- Start Internet Explorer 7. Go to Tools > point to Manage Add-ons >
    click Enable or Disable Add-ons. Now enable a single add-on, then exit
    and restart Internet Explorer 7 to see if it works properly. Repeat
    until you determine which add-on causes the problem to occur.

    Once you've located the troublemaking add-on(s) ask the vendor's
    technical support for help.

    => Does the behavior persist if you start IE7 in No Add-ons mode? To start
    IE7 in No Add-ons mode:

    1. Right-click on the blue IE desktop icon and select Start without Add-ons;

    2. Start | (All) Programs | Accessories | System Tools | Internet Explorer
    (No add-ons).

    Troubleshooting and Internet Explorer's (No Add-ons) Mode:

    => Does the behavior persist if you boot into Safe Mode with Networking?

    I had hoped for a better routine:

    My IE7 began freezing for no apparent reason some weeks ago. Although I have
    experienced (I believe) two freezes during the same day the typical pattern
    is that I can operate my computer for many days with no problem and then
    suddenly IE7 is frozen and will not respond when I bring it forward from

    My Add-on manager tells me (every time I ask) that I have seven add-ons that
    are not "Add-ons that run without requiring permission", i.e. certified
    add-ons, I have disabled all of those in the manager. In addition I have two
    or three (varies) Add-ons that are certified; IE7 complained immediately
    when I disabled them so I have enabled them again. The seven uncertified
    add-ons have all been disabled since yesterday morning.

    Yesterday I ran my computer for ten consecutive hours before I suddenly
    found IE7 frozen. The freeze must have occurred during the last hour before
    I discovered it.

    Today I have now run my computer in two sessions: one for about six hours
    and the current which was started about five hours ago. So far there has
    been no problem today.

    The first and most important question now is this: Can I trust that a loaded
    but disabled add-on will not be able to cause any problem?

    If the answer to this question is "yes" then I know for certain that the
    freeze is not caused by any uncertified add-on in my system unless there is
    an add-on that freezes IE7 immediately when it is loaded. (How can I in case
    "capture" such a failing load?)

    And if the answer to my question is "no way" then my next question is of
    course about the meaning of an add-on being "certified".

    I'll stop right there for now, hoping for an answer that can enable me to
    find out more.

    I'm sorry, Sven, but I can't help you unless you complete the
    troubleshooting procedures all the way through and report back on your
    results. Otherwise we're just speculating and taking lucky guesses.

    Please see my other post about the rest of your questions, but note that I
    just discovered one piece of information that can be important:

    I have an add-on named SSVHelper Class from Sun Microsystems Inc. Apparently
    this exists on my system both as a browser type and as ActiveX type , the
    one loaded on my system is the browser type.

    The ActiveX type is listed among "Add-ons that run without requiring
    permission", the browser type is not. Therefore, until now (yesterday and
    today) I had not disabled this add-on, but from now on also that one is

    Consequently, if my system now runs for several weeks (!) without problems I
    shall have very strong circumstantial evidence that the freeze has been
    caused by this add-on, but if I get another freeze I suppose I shall have
    equally strong evidence that the problem must be something else, i.e. within
    IE7 or its certifiec add-ons?

    I have a feeling that because of the scarce occurrence of the freeze the
    tests suggested below will be of very limited value?

    But I am very interested in comments and suggestions.

    I don't understand why I cannot receive an answer to my question whether or
    not I can trust a "disabled" add-on to not possibley cause any problem?

    As noted in my answer to PA Bear I discovered one loaded add-on that I
    thought I had found in the list of certified add-ons acutally is not.This
    add-on is a browser type, the certified one is an ActiveX type. I have now
    disabled also this add-on.

    The only add-on that are now enabled on my system is an ActiveX-type
    "Shockwave Flash Object" from Adobe Systems Incorporated. When I tried to
    disable also this one my IE7 complained immediately when I tried to start it
    so I have left this add-on enabled.

    Based on my experience so far on how long time it can take between two
    occurrencies of IE7 freezing I expect that the necessary verification time
    needed to be fairly sure my system is free of the problem is more than a
    full week operation, maybe two weeks without IE7 freezing. That makes some
    of the recommended tests not very feasible.

    This is also why I have posted specific questions that I expected to be
    fairly easy to answer by someone who knows the system better than I do.
    Please don't disappoint me?

    Info to anyone that might be interested:

    I have done some Google search on SSVHelper Class and found several
    indications that this add-on quite likely is the culprit in my problems. It
    is part of a Java update, and the time this update was released seems to
    match pretty well the time I started experiencing the problem.

    According to what I found there is at present no other known solution to
    this problem than to disable the add-on, and I found no indication that
    disabling it can cause other problems.

    regards Sven (in the hope that my system will be stable again)

    same answer(s) in other replies, please.]

    Are you running Vista or Vista SP1?

    Have you tried Resetting IE Advanced Settings (RIES)?

    Is Sun Java runtimes (JRE) v1.6.0_10 or higher installed?

    Vista SP1, Home premium, fully updated.
    No, not yet. As I have written the freeze occurs so unpredictably that it
    would take weeks to verify with some confidence that the problem has
    disappeared using these "standard" (brute force) trouble-shooting methods. I
    wasn't too happy about resetting everything as the first choice, not knowing
    then what was important if the problem just disappeared. Just disabling
    add-ons seemed a better way once I learned about it.
    According to the Control panel I have Java SE Runtime Environment 6 from Sun
    Microsystems Inc. installed. It doesn't tell which version.

    Having accidentally left SSVHelper Class enabled when I disabled all the
    other "un-certified" add-ons and experiencing a freeze already after some
    ten hours operation this add-on is obviously now my prime suspect. I am
    puzzled by the existence of both a browser type and an ActiveX type of this
    add-on to my system?

    I intend now to run with all eight "un-certified" add-ons on my system that
    are loaded disabled for at least a week, and then begin enabling the other
    add-ons one at a time as long as the system seems stable.

  11. I'm afraid that RIES may be one troubleshooting step you might have to take.

    I have been dealing with IE7 freezing up every time it was started for the
    last month. It had no problems running if I started it with no add-ons.
    After following PA Bear's instructions as stated above; I disabled all
    add-ons and stepped back through enabling one at a time until I found the

    The "IE7Pro BHO" add-on was locking it down at every startup.

    I have not researched this add-on's intended purpose yet and I can't claim
    to be any kind of Guru at stumbling through many of Vista's other headaches
    throughout my system, but this did fix atleast one sore spot for me.

    Now if anyone would like to bestow any wisdom about the IE7Pro BHO add-on,
    upon me. Should I look for a fix? Do I even need it? What does it suppose
    to actually do other than lock up IE7 all the time?

    This is my first post here. I hope it is posted correctly.

    "AskJava" (Method 1) returns nothing - only a small red X within a small
    square (where it says that I should see a pink rectangle if Java is working)
    indicating (I suppose) that a frame URL could not be resolved?

    OK, I enabled Java(TM) SE Runtime Environment and Sun Java Console again
    (but not SSVHelper Class)

    Now "Method 1" shows: "Java Version: 1.6.0-oem from Sun Microsystems Inc."

    And a few minutes ago my IE7 suddenly froze while I was browsing.

    I closed IE7 and then started it again, disabled "Sun Java Console" and then
    closed and started IE7 yet again.

    "Java(TM) SE Runtime Environment" doesn't show up in any list now, not in
    "Add-ons currently loaded in Internet Explorer" nor in "Add-ons that have
    been used by Internet Explorer" so I cannot disable that add-on.

    Looking back I have no record of disabling this add-on, however I distinctly
    remember that I enabled it together with Sun Java Console in order to use
    the Java version helper?

    Frankly I don't know if I simply remember enabling a loaded add-on that was
    already enabled, and I don't know if this means anything at all.

    The fact is that my IE7 froze with Sun Java Console enabled although
    SSVHelper Class was disabled, and that IE7 previously froze when SSVHelper
    Class was the only enabled browser type add-on.
